Southland District Council (SDC) has more than 1,000 km of unsealed roads in its Central Area. These range over a distance of about 50 km east-west, and 70 km in the north-south direction. The maintenance contract requires that Contractor Works Infrastructure Limited (Works) manages the underpinned quantities, and hence it is important that work is targeted appropriately. In order to limit the amount of reactive maintenance activity, and to lift activity to a more strategic level, a programme of information-gathering of simple data has been commenced to prioritise locations where structural, surface or drainage maintenance activity is called for. A single numerical measure of need is calculated, and its components are subsequently examined. The pros and cons of this approach are discussed, including its ability to limit “scatter gun” reactive maintenance. (a) For the covering entry of this conference, please see ITRD abstract no.
